This code is based on a series of leonardo Da Vinci DM6446 driver development of embedded development sample program, the program package contains C language source program demo. C, test_demo. C and Makefile.The program simple, showing that the frame structure, the driver and the embedded driver development steps, introduction to the embedded driver development comrades are very helpful.After repeated the test and operation of the program, there are no errors, can be directly run. Commissioning procedures 1, carefully read the catalog code: demo. C, demo. J h, test_demo. C. Analysis of the function of each part of the code, as well as the applications and drivers call, the method and flow of data reading and writing. 2 Makefile, carefully read the directory, understand the function of file each statement. Enter the directory where the files on the host, input: make generated need driver. Input: make app generated need application. 3, enter the minicom or super terminal, will tes
